Ok, so I've been away for a few days and the cat (I think, I hope) has managed to knock over a jar of beet root (empty but full of juice) I was intending to wash and stick in the recycle bin. The juice has dried in the grout of the tiled floor. The steam mop just isn't getting it out and I've scrubbed it with fairy. The steam mop says add nothing to the water but can I put bleach on the grout and use the steam mop to clean it?
